Benefits of technology

The present disclosure describes an articulation mechanism for a surgical instrument that allows for smooth and efficient articulation of the instrument. The mechanism includes a housing with a receptacle and a shaft with an articulation member and a translation member. The articulation member is positioned on the outer end of the shaft and includes a spiral groove or slot and a pin assembly that engages with the spiral groove. The translation member is mounted within the housing and includes a spring loaded slide and plunger to provide audible and tactile indications of the degree of rotation and the neutral position of the translation member. The housing is a rotatable member that can be used with a surgical instrument and includes a mechanism cover to support the rotatable shaft. The technical effects of this mechanism include improved articulation of the surgical instrument, reduced articulation time, and improved precision and efficiency during surgical procedures.

Problems solved by technology

Such practices increase the time, complexity and overall costs associated with laparoscopic surgical procedures.
In addition, costs are greater in designing and manufacturing multiple stapler sizes, as opposed to creating a single, multipurpose stapler.

Embodiment Construction

[0107]Preferred embodiments of the presently disclosed endoscopic surgical stapling apparatus will now be described in detail with reference to the drawings, in which like reference numerals designate identical or corresponding elements in each of the several views.

[0108]In the drawings and in the description that follows, the term “proximal”, as is traditional, will refer to the end of the stapling apparatus which is closest to the operator, while the term distal will refer to the end of the apparatus which is furthest from the operator.

[0109]FIGS. 1-3 illustrate one embodiment of the presently disclosed surgical stapling apparatus shown generally as 10. Briefly, surgical stapling apparatus 10 includes a handle assembly 12 and an elongated body 14. A disposable loading unit or DLU 16 is releasably secured to a distal end of elongated body 14. Disposable loading unit 16 includes a tool assembly 17 having a cartridge assembly 18 housing a plurality of surgical staples and an anvil as...

Abstract

An articulation mechanism for use with a surgical apparatus having an articulating tool assembly is described. The articulation mechanism includes a rotatable shaft which is fixedly secured to a disk defining a spiral groove or slot. A linearly movable translation member is provided and includes a pin which is received within the spiral groove such that rotation of the disk effects linear translation of the translation member. The configuration of the spiral groove can be selected to provide any desired ratio of angular rotation of the disk to linear advancement of the translation member. As such, the configuration of the spiral slot can be selected to provide a uniform rate of articulation of the tool assembly of the surgical apparatus or a variable rate of articulation.

Description

BACKGROUND[0001]1. Technical Field[0002]This application relates to a surgical stapling apparatus, and more particularly, to an articulating mechanism for use with an endoscopic surgical stapling apparatus for sequentially applying a plurality of surgical fasteners to body tissue and optionally incising fastened tissue.[0003]2. Background of Related Art[0004]Surgical devices wherein tissue is first grasped or clamped between opposing jaw structure and then joined by surgical fasteners are well known in the art. In some instruments a knife is provided to cut the tissue which has been joined by the fasteners. The fasteners are typically in the form of surgical staples but two part polymeric fasteners can also be utilized.[0005]Instruments for this purpose can include two elongated members which are respectively used to capture or clamp tissue. Typically, one of the members carries a staple cartridge which houses a plurality of staples arranged in at least two lateral rows while the ot...
